Huarón is located in the district of Huayllay, province and department of Pasco, on the slope of the Andes, central area of the country, at 4534 m above sea level. The exploitation method used in this is a combination of conventional cutting and filling, machined cutting and filling, and deep drilling machining.

Anddes contributes to the success of the Huarón project by:

  • Anddes contributes to the success of the Huarón project, through:Review of the feasibility of the closure of tailings deposits 1, 2 and 3, through the growth with mine stripping material.
  • Construction quality assurance (CQA) growth Tailings Dam N°5.
  • Earthmoving work. Detailed engineering of tailings dam growth with reinforced wall.
  • Detailed engineering of the tailings reservoir closure design 1,2 and 3.
  • Monthly visits to verify the status of the tailings dam and technical reports.
  • Supervision of the instrumentation work of the tailings dam and the grouting injection work in an area of the dam.
  • Safety inspection of tailings dam. Study of breakage of tailings dam.
  • Characterization of tailings and clays in the foundation of the dam.
  • Processing and interpretation of geotechnical monitoring.
  • Development of a tailings disposal manual for the current tailings dam situation.
  • Infiltration and stability analysis considering the current geometry of the dam.
  • Updating and optimization of rainwater management impacting on tailings dam N°5.
  • Updating of the mine tailings handling and disposal system. Project of tailings production and various uses.
  • Analysis and recommendations of the plan and sequence of growth of the tailings dam according to the current production plans of the mine.
  • Implementation of a comprehensive plan for the entire water and tailings management system of the mine.
  • Detailed engineering of the growth from the height 4446 msnm to the height 4449 msnm.
  • Updating the design of the spillway and the extension of the existing quenas to the level 4455 msnm of the tailings dam N°5.
  • Plan of disposal of tailings in the tank N°5 to ensure the correct functioning of the spillway and quenas.
  • Monthly interpretation of the geotechnical data of tailings dam N°5.
  • Quality assurance of the construction (CQA) of earthmoving and concrete works of the recreeding of tailings dam N°5 (elevation 4447.5 to 4449.0 masl), emergency spillway and quenas at 4455 masl, including buttresses B and D, downstream of the dam.
